Air conditioner and refrigeratory system for LNG ship

Abstract

The invention relates to an air conditioner and refrigeratory system for a LNG ship and belongs to the field of air conditioner for a ship. The invention discloses the air conditioner and refrigeratory system for a LNG ship, comprising a cold carrying module, an air conditioner module and a refrigeratory module, wherein the cold energy input end of the cold carrying module is connected with a cold source body, and the cold energy output end of the refrigeratory module is sequentially connected with the refrigeratory module and the air conditioner module; the air conditioner module comprises a heating module, a cooling module and a blowing module, wherein the heating module is connected between a heat source body and the blowing module, and the cooling module is connected between the cold carrying module and the blowing module; and cold energy of the cold source body passes through the cold carrying module and then sequentially enters the refrigeratory module and the cooling module, the cooling module is used for transferring obtained cold energy to the blowing module to refrigerate air, and heat energy of the heat source module is transferred to the blowing module by the heating module so as to heat the air. The system can effectively achieve economical use of energy, is easy to popularize, can improve the energy utilization rate of the LNG ship, and can lower the ship cost.

Description

Technical field [0001] The invention involves a LNG ship air conditioner and frozen library system, which is the field of ship air conditioning. Background technique [0002] Ship sails in various seas, with complex weather conditions and changing climate. In order to make crew and passengers have a comfortable life and working environment, air -conditioning technology can use air -conditioning technology to create a suitable artificial climate in the cabin and improve the environment.Existing ship air conditioners are generally electric air conditioners or oil -driven to drive, but when ship sailing, due to difficulty in power supply or difficulty in oil supply, how to reduce air conditioning energy consumption has become a problem that needs to be resolved, especially for the LNG ship.For example, how to use LNG's cold can solve the effective means of reducing the energy consumption of ship air conditioning.And in the existing energy cycle control, due to the low temperature of...

AI Technical Summary

Problems solved by technology

The existing marine air conditioners are generally driven by electricity or oil, but when the ship is sailing, due to the difficulty of power supply or oil supply, how to reduce the energy consumption of air conditioners has become a problem that needs to be solved, especially for LNG ships. Therefore, how to use the cold energy of LNG is an effective means to reduce the energy consumption of marine air conditioners

Moreover, in the existing energy cycle control, because the temperature of LNG is too low, it is not suitable to be directly used for air conditioning control and cooling. Otherwise, the life of the equipment will be significantly affected by the change of temperature difference, and more special pipelines are required. For LNG transportation, increase the cost of use and installation
